Abstract
The utility model relates to an electric control device for a heater of an electric food warmer. The electric control device comprises more than one group of electric heaters, more than one resistor, a temperature controller and a gear switch, wherein one end of each electric heater and one end of each resistor are connected with the output end of the gear switch respectively; the other end of each resistor is connected with the N end of commercial power through the temperature controller; and the other end of the electric heater is connected with the N end of the commercial power. The electric control device is characterized by further comprising a timer, wherein one end of the timer is connected with the L end of the commercial power; and the other end of the timer is connected with the input end of the gear switch. The electric control device has the advantages that: a power supply can be switched off manually, the power supply can be switched off automatically at set time as required, the service life of the electric heater is long, and convenience is brought to use.
Description
Technical field
The utility model relates to a kind of electric control gear of heater of electric food warmer.
Background technology
The electric control gear of the heater of existing electric food warmer; Comprise one group of above electric heater, the resistance more than one, temperature controller and driving switch; One end of wherein said electric heater and an end of resistance connect the output of driving switch respectively; The other end of resistance is through the N end that connects civil power of temperature controller, and the N end of another termination civil power of electric heater component, the input of driving switch pass through the L end of insurance wire connection civil power.During use, because not free control needs artificial power cutoff, if forget power cutoff, electric heater is being worked always, uses inconvenience, also influences the service life of electric heater.
Summary of the invention
The utility model is to overcome the deficiency of prior art and a kind of free controller is provided, promptly can artificial power cutoff, again can be by the required time automatically cutting off power source that configures, and the electric control gear of the heater of the electric food warmer of the long service life of electric heater.
In order to achieve the above object; The utility model is achieved in that it is a kind of electric control gear of heater of electric food warmer, comprises one group of above electric heater, the resistance more than one, temperature controller and driving switch; One end of wherein said electric heater and an end of resistance connect the output of driving switch respectively; The other end of resistance is through the N end that connects civil power of temperature controller, and the N end of another termination civil power of electric heater is characterized in that also comprising timer; The L end of said timer one termination civil power, the input of another termination driving switch.
It is identical that the group number of said electric heater and the number of elements of resistance and the gear number of driving switch subtract a back.
The utility model advantage compared with prior art is: promptly can artificial power cutoff, again can be by the required time automatically cutting off power source that configures, and the long service life of electric heater, easy to use.
